Abstract

The invention discloses a corrosion-resistant magnesium-aluminum honeycomb ceramic heat accumulator and a preparation method thereof, and the corrosion-resistant magnesium-aluminum honeycomb ceramic heat accumulator characterized by being prepared mainly from the following components: 20-30 parts of silica, 20-30 parts of titanium dioxide, 10 to 20 parts of dense fused corundum fine powder, 5 to 10 parts of iron oxide, 5 to 15 parts of chrome oxide green micro powder, 5 to 15 parts of chrome ore powder of 0.1 to 1 mm, 2 to 4 parts of aluminate cement, 1 to 3 parts of silicon micropowder, 3 to6 parts of chlorinated polyethylene, 3 to 5 parts of maleic acid-acrylic acid copolymer, 10 to 12 parts of hydroxypropyl methylcellulose, 2 to 3 parts of phthalic acid ester, 2 to 3 parts of monoethanolamine and 1-3 parts of stearic acid by stirring, casting molding, drying and calcining. The corrosion-resistant magnesium-aluminum honeycomb ceramic heat accumulator has a large viscosity coefficient and extrusion pressure lower than that of other mud systems, and has little wear on equipment. At the same time, the corrosion-resistant magnesium-aluminum honeycomb ceramic heat accumulator has good drying properties and does not crack in the air for two hours.

Description

technical field [0001] The invention relates to the field of manufacturing honeycomb ceramic regenerators, in particular to an erosion-resistant magnesium-aluminum honeycomb ceramic regenerator and a preparation method thereof. Background technique [0002] Honeycomb ceramics are widely used in regenerators, catalysts and their carriers, and ceramic membrane carriers for flue gas filtration due to their large specific surface area, large heat capacity, small thermal expansion coefficient, good high temperature resistance, and strong corrosion resistance. Especially in the field of regenerative combustion technology, regenerative honeycomb ceramics are widely used in industrial kilns such as heating furnaces due to their good heat storage and release performance, high temperature performance and thermal shock resistance. With the development of regenerative combustion technology and the emergence of direct reduction ironmaking technology, a honeycomb body with strong resistan...
